The passage discusses a new theory regarding the purpose of the appendix

Answer Choices (A) Researchers found that the biofilm coating the appendix allowed-helpful bacteria to thrive

in the appendix

(B) When the intestine was emptied completely, researchers found that helpful bacteria

returned to the intestine very quickly

(C) The appendix is covered in a thin coating of mucus, immune molecules, and bacterial colonies

(D) Researchers concluded that the appendix could act as an area to hold reserves of helpful

‘bacteria

(E) Rabbits, possums, and wombats also have appendixes

(F) Since a functioning appendix is difficult to actively observe, discovering its purpose can

be difficult

The appendix in humans is different from those found in other animals, which makes it difficult to.understand the function of the organ Doctors believe it is helpful in protecting the intestines from harmful bacteria, even though the appendix does

ead the following passage Then fill in the diagram with the information that you read

Personality disorders are a class of mental disorders They affect

"the way people view themselves, other people, and the world around them Personality disorders are broadly classified They include multiple-

personality disorder, which describes a person who thinks of himself

as more than one person He behaves differently according to each personality They also include extreme narcissism This describes a person who focuses on herself so much as to severely hinder her

behavior and perceptions of the world Personality disorders are typically identified by psychologists late into their development Thus,

_their original causes are difficult to pinpoint There are a number of

* possible factors, however, that may contribute to the formation of a

“ personality disorder

The most obvious factor—and perhaps the easiest to identify—

are biological causes Particular traits that infants inherit from their parents may contribute to the development of a personality disorder

,, Some researchers have also suggested that there may be a genetic

-basis, independent of heritable traits, that makes an individual more

‘< likely to develop certain disorders However, it has been determined

5 that nearly all known personality disorders are not caused entirely by

“genetic makeup Socio-cultural and other psychological factors

inevitably play a role

Psychological factors are most likely to play a role in personality

- ‘disorders {tis believed that individuals are most affected by experiences

‘early on in life Interestingly, there is very little research to support this Notion One study reported that seventy-one percent of patients.with borderline personality disorder claimed that they had been abused

as children Another study found that eighty-one percent of borderline patients reported some form of trauma in early childhood However, such evidence is by no means conclusive The research is based on the reports of patients already believed to have a personality disorder

As a result, their perceptions of the past may be distorted A patient with

borderline narcissism disorder, for instance, may exaggerate a past experience because of his sense of self-importance Further research has suggested that perceived trauma may not have actually occurred early on in a patient's life, but rather much later As such, it is unclear how much of a role traumatic situations have on one’s personality Many experts suspect @ connection Nonetheless, they are unable to verify it

Social factors are also thought to play a significant role in the

development of personality disorders, perhaps more than any other

Some researchers, for instance, have argued that infants go through

a phase in which they believe that all events of the world revolve

around them in most individuals, this phase eventually passes and

infants come to terms with social reality However, this period is key in

helping individuals retain:a sense of self-confidence lf parents do not

provide some assurance that their child deserves respect and attention,

he or she may develop a personality disorder Conversely, others have argued that too much attention from parents during childhood can result in the development of a narcissistic personality disorder —

Some psychologists have gone so far as to suggest that socio-

cultural factors may contribute to personality disorders These theories

go beyond simple social situations on an individual level They suggest that one's culture can afféct personality People, for instance, brought

up in an oppressive society and taught that they exist only to serve the state may, on returning to normal conditions, feel overwhelmed by

‘the attention they get as individuals As a result, they may experience

“severe anxiety when asked to talk about themselves Other theories suggest that many developed nations are responsible for the expectation

of individuals that material goods provide meaning Given the broad nature of socio-cultural theories of personality disorder, they are nearly impossible to prove or disprove They remain, however, a source of

debate for most psychologists

_ Our understanding of personality disorders is by no means complete

Their causes may vary dramatically from person to person Psychologists have been criticized because they claim to know what is ‘normal

They serve as the arbiters of what is unusual In addition, some have questioned the usefulness of broadly identifying contributing factors

to personality disorders Each individual case varies Clearly, further research must be done to adequately identify not only causes and

treatments, but also what is and what is not a disorder

Hard drives and storage devices produced in the past fifteen years have been significantly smaller than their predecessors This change would not have been possible without the contributions of European scientists Albert Fert and Peter Grinberg The two men, independent of

each other, discovered a previously unobserved phenomenon in physics

It would change the face of technology and its practical applications

in everyday life The phenomenon they observed was dubbed Giant

undiscovered until they observed it in 1988 Their observation was based

on the principle that electricity and magnetism are directly associated

Both scientists discovered that very small changes in magnetic resistance could result in rather dramatic changes in corresponding

electrical resistance While it may not seem immediately réléVant-to

technology, the discovery was important in creating srnall devices capable of holding large amounts of data

The hard drive of a computer is the best example of how the

discovery of GMR changed everyday technology: The data stored on

hard drives is encoded on a metal disk An: encoding process

magnetizes small sections of the disk, which in turn are translated

into data when the magnetized disk is read by a sensor The sensor

translates the magnetic data into electric signals Hard drives prior to the discovery of-GMR were significantly larger than those we have today Although they operated based on the same basic relationship

of magnetism and electricity, it was difficult for sensors to discern between separate pieces of data without a very large disk Therefore, the disks used for high-capacity hard drives were much larger than a dinner plate The insights of GMR, however, allowed engineers to -shrink the hardware, while retaining and even increasing the storage

capacity

Using the principle discovered by Fert and Grinberg, the first hard drive using GMR technology was released in 1997 It quickly

became the standard, thanks to its compact size The insights of GMR allowed engineers to increase the sensitivity of the sensor heads on hard drives As a result, the size of the magnetic strips of data on a

hard drive could be drastically reduced In fact, these sensor heads

are so sensitive that the magnetized strips of data may only be a few atoms thick The discovery and implementation of GMR would not

have been possible without discoveries that allowed very thin material

of this small size to be produced GMR hard drives put a very thin

The contribution of GMR to modern technology was massive

Hard drives prior to the application of the technology were much

larger in size and-relatively small in storage capacity High-capacity drives were sometimes as large as chairs With the new technology, hard drives the size of a human hand could be engineered to.hold as much data as their high-capacity, non-GMR counterparts Furthermore, researchers quickly found that additional magnetic layers, separated

by a nonmagnetic layer, could be used to store even more data Since the additional layer is only a few atoms thick, it does not substantially

change the size of the hard drive, Additionally, the development has been accredited with contributing to the field of nanotechnology, an

emerging technology concerned with the engineering of microscopic

devices Since GMR requires hard crives to use a disk plated on a magnetic material only a few atoms thick, it contributed to technology

that is now being used to engineer compiex mechanical devices of a

“and bulky, today’s laptop computers are less than an inch thick The end

“result of the discovery of GMR is still not completely apparent We

continue to use it in everyday technology, but that technology is

constantly being honed and improved with time As such, it is unlikely that we have seen the last of what GMR has to offer us ,
